tried again with 4.19rc2. Stripped off all other usb peripherals (including existing mouse & kb), only had the internal (windows) SSD and the usb one I am plugging in. Now using a logitech K400 or so, which seems compatible with everything. When I boot, it dumps me into (initramfs) prompt, and I can use it. If I do ls /dev, I see sda, sda1, sda2, sda3 and no other disk partitions. When I try to mount them, I find they are the windows SSD that is SATA connected. It doesn't see the externally USB connected drive.
So I disconnected the windows SSD, removed the other SSD from the enclosure and connected it the ubuntu SSD via SATA. Now I can get a reproducible crash. picture coming. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1753510 Title: Cannot boot/install AMD Ryzen 2400G To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1753510/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
